HypT2mean The two-sample T-test for the difference of two means.

HypT2mean((x

, n

, α,pooled,mode,

[”configuration”])

Pooled: Specifies whether or not the samples are pooled

• 0: not pooled

• 1: pooled

Mode: Specifies which alternative hypothesis to use:

• 1: μ

< μ

• 2: μ

> μ

• 3: μ

≠ μ

Configuration: a string that controls what results are shown

and the order in which they appear. An empty string ""

displays the default: all results, including headers. The options

in the configuration string are separated by spaces.

• h: header cells will be created

• acc: the test result, 0 or 1 to reject or fail to reject the null

hypothesis

• tT: the test T-value

• tM: the input Δ value

• prob: the lower-tail probability

• cT: the critical T-value associated with the input α-level

• cx1: the lower critical value of Δ associated with the

critical T-value

• cx2: the upper critical value of Δ associated with the

critical T-value

Example:

HypT2mean(0.461368, 0.522851, 0.2776,

0.2943,50, 50, 0, 0.05, 1, "")
